Abstract (en)

[origin: ES8103124A1] An acid-hardening low shrinkage cement based on a furan-modified phenolic resin containing as a binder (A) a reaction product of furfuryl alcohol with a hydroxymethyl group-containing substituted phenol resol, based on a substituted phenol selected from the group consisting of bifunctional alkylphenol, an aralkylphenol each having 3 to 20 carbon atoms in the alkyl radical, an arylphenol or a combination thereof with a minor amount of one or more unsubstituted phenols, wherein in the substituted phenol resol at least 75% of the reactive H-atoms of the nucleus are substituted by reaction with formaldehyde and wherein more than 0.5 mol of furfuryl alcohol has been reacted per hydroxymethyl group together with (B) at least one reactive diluent in a weight ratio of (B):(A) in the range from (0.4 to 1.5):1, and a process for the preparation of said composition.
